The annual CP-AI-OR conferences bring together interested researchers from constraint programming (CP), artificial intelligence (AI) and operations research (OR) to present new techniques or new applications in combinatorial optimization and to provide an opportunity for researchers in one area to learn about techniques in the others. A main objective of this conference series is to give these researchers the opportunity to show how the integration of techniques from different fields can lead to interesting results on large and complex problems. The conferences are also a forum to showcase the effectiveness of CP/AI/OR techniques on challenging combinatorial optimization applications and to report on successes and limitations of these techniques when deployed in an industrial setting.
